Patented Oct. 7, 1913. a SHEETS-SHEET a crank-.shaft 33 extends Within and loosely through a bevel pinion' 36Witliin saidY case, which pinion meshes.. ith 'the bevel pinions 28 and 30 at diametrically 01pposite points. The. inner end portion of the crank-shaft' 33 carries a transverse"pin 37 adapted tobe vreceived at times inv notches 38 in the hub of' the pinion 36 to connect saidshaft and pinion for conjunctive rotation. The bearing 34 is `fixed to and rises froma stationary member 39 in this instance a `portion of the cover of the tub. A

movable member 40, such as in this instance a cover for the tub, is connected by arched hinges 41 to the stationary member The movable member is provided with a latch 42 opposite to the hinges 41 whereby it may be detachably secured to the support or tub l0 in closed position. A set eollar 43 is mounted on the crank-shaft between the bearings 34 and 35 and is spaced from both bearings. i A cam lever 44 is pivot-ed one end on the crank-shaft 33 between the set collar 4 3 and bearing and is formed With one or more cam lugs 45 tted to notches in the ad) arent end of the bearing 34. A link 46 1s pivoted at one end to the inner end of the cam lever 44 and extends obliquely downwardly therefrom and is pivoted at its between its ends.

lower end to an angle ',olate 47 on the mov able member 40 of the tub top. The cam lever 44 is formed 'with a stop or lug 43 aset screw 50 on the outer end of the crank shaft 33 andan expansive. coil spring 5l is mounted on said crank-shaft and impinges at its respective ends on the-bearing 34 and the hub of the crank 49. lt is the function of the coil spring 5l to move and hold the crank-shafty outwardly longitudinally in its bearings to the end of inserting the pin 37 in the notches 38 and connecting the pinion'36 and crank-shaft for conjunctive rotation. 'It is the function of the cam lever 44, acting through the cam lugs 45 and adjacent end of the bearing 34, to move the crankshaft 33 longitudinally in its hearings against the expansive force of the spring 5l. It is the function of the stop or lug 48 to engage the link-46 and support the movable member 40 in open position out of contact with the gear case or bearings ad A device to be driven7 such as a dolly7 shaft or agitator shaft 52, is mounted loosely in a hole in a plate 53 fixed to the movable member 40.

is adapted forrotation and also for'rectilinear reciprocation therein and through the plate 53. vA cranloarm 54 is formed With an angular laperture .in one end receiving and fitting loosely to the shaft 52 and said crankarm lies on and is'movable through an are m a plane parallel with. the plate' 53.

ie 'gear case being in turn 'pivoted to the crank 49.

A. crank 49 is secured b v The shaft 52 also extends loosely through the movable member 40 and A. lever 55 is fulcrumed at one end on a stud '56 rising from the plate 53. The lever 55 is of skeleton form,' having a large aperture or opening 57 through which the shaft 52 may pass and said opening is of such shape as to permit the lever. to be moved through an are approximating a half circle across the shaft52. A pin 53 rises from the outer end portionl of the crank-arm 54 into a `groove .59 formedv in and longitudinally of the outer end of the lever 55. By .means of the nin 58 andgroove 59 motion is trans mitted .from the lever 55 to the crank-arm 54 to the end of rotating the shaft 52.

. A Dblock 60 is pivoted at one end on a stud 6l rising from the free endof the lever vthe lever and shaft devices on the movable member 40 and the shaft and crank devices carried by the bearing 34, which permits the free and uninterrupted movement of the movable'member and devices carried thereby through an arc by articulating on the hinges 4l. Y

lt will be observed that when the movable member 40 'is moved. into open position the shaft 33 is disconnected from. the pinion 36v vand becomes stationary, thus stopping any movement-.of the lever and sha ft devices on said movable member.

The countershaft 26 carries rigidly a pmv ion 64, Which: pinion meshes With the pinion 25 and preferablyhas longer teeth than the latter pinion in order 4thaty itmay remain in mesh therewith throughout the range'of movement of the countershaft longitudi-v nally.

A bracket is'mounted on'the member '16 at the opposite end ofltlefvvringer 22 from `the gear case l5 and abellcrank 66 is fulrrumed on said bracket lvandf-'hasgone'of its arms extending outward'. iorizontally and the other upright'therefrom. lThe extremity of the upper; arm of the l.bell-'crank 66 is hifurcated and it embraces" a grooved set collar 67 on the adjacent end portion of the lOb countershaft 26. The lower 4arm of the bell.-

Crank 66 is pivo-ted at its outer end to the upper end of a rod 6 8 and the lower end of said rod is 'pivoted to aytreadle v69 'or pivoted et one end to a plate'70. carried by the legsy il of the and isupheld pedallv-operated lever; The treadle 69 is ioIV ' slot 7 2 and, acting invente normally by a retractile coil spring 7l connecting said lever to the bottom of the support. T he outer end portion of the treadle 69 extends through a 'slot 72 in a plate 73 mounted in upright position on one of the legs 11. The plate 73 is formed with a shoulder Tet in the slot 7 2 and the treadle may be arranged in engagement with the shoulder to hold the countershaft 26 in neutral position as shown in Fig. 4, the lugs 29, 3l and 32 being wholly disengaged; In the neutral position as shown the shaft 26 is stationary-and does not operate the wringer i'olls in either direction. .01', the treadle may be adjusted into the upper part of the through the connections therewith, will move t e countershaft 26 so as to bring the studs 29 into engagementwith the hub of the bevel pinion 28 and cause said shaft to be rotated inv one direction and in turn rotate the wringer rolls.l

0r, the treadle 6 9 mav be depressed pedally to the bottom of the slot 72 and in such position act through the connections therewith and move the countershaft 26 in the opposite direction so as to disengage the studs 29.

from lthe bevel pinion 28 and engage the 4studs 3l with the studs 32 on the bevelpinion 3Q to. the end of driving the countershaft in .the opposite direction rotatively through the medium of the latter bevel -pinion and in turn' driving the wringer rolls in the opposite direction.
